ᐉ Trends: Melting Point and Atomic Radius Across Period 3

WebGenerally the melting point of the metals decreases down the group. This is because as the metal ions get larger the distance between the bonding electrons and the positive nucleus gets larger and reduces the overall attraction between the two. For similar reasons the electronegativity decreases.
